(±)-2, 4, 5- and 2, 4, 8-Trihydroxy-1-tetralones (2, 9, 3, 11) were synthesized from juglone, and their cytotoxic activities against Yoshida sarcoma cells were examined. The trihydroxytetralones were more cytotoxic than dihydroxytetralones. While the configuration of the hydroxyl groups in the alicyclic ring scarcely affected the cytotoxicity against Yoshida sarcoma cells, the position of the hydroxyl groups in the aromatic ring seem to be important. The 2, 4, 8-trihydroxytetralones (3, 11) were more cytotoxic than the 2, 4, 5-trihydroxy derivatives (2, 9).
(±)-2, 4, 5-和2, 4, 8-三羟基-1-四氢
萘酮(2, 9, 3, 11)是由胡桃
酚合成的,并检查了它们对吉田肉瘤细胞的细胞毒性活性。三羟基四氢
萘酮的细胞毒性比二羟基四氢
萘酮更强。虽然环状烃环中羟基的位置对吉田肉瘤细胞的细胞毒性影响不大,但芳香环中羟基的位置似乎很重要。2, 4, 8-三羟基四氢
